Hi!

While rebuilding packages against python 3.15 we found that cython
produces some errors when used against it. Some of this caught by the
autopkgtest
(https://debusine.debian.net/debian/r-python-python3.15/work-request/972899/)
.

I'm attaching a debdiff that adds the upstream fixes related to python
3.15, these fix the build against python 3.15, these fixes are in the
history of the upcoming 3.3.0 release.

I'll also send a merge request for this changes to salsa which might be
easier to work with depending on your workflow.

Happy hacking,
